Carbyne is the strongest material in the world - 2x stronger than graphene
Carbyne is the world's strongest material - about 2x stronger than graphene or carbon nanotubes which, until now, were the strongest known materials by some margin. Carbyne is stronger & stiffer than any other known material to humans. It's a new form of carbon that has a long list of unusual and highly desirable properties and can find wide range of applications from nanoelectronic / spintronic devices to hydrogen storage and high-density batteries.
Carbyne is also known as acetylenic carbon is an infinitely long chain of carbon atoms put together by sequential double bonds or alternating single / triple bonds. So far, Carbyne remained a mystery for the scientists. Researchers at the Rice University, led by Mingjie Liu, calculated the properties of carbyne using mathematical models and knowledge of carbon atoms. They found out that Carbyne has extremely high tensile stiffness - making it almost impossible to stretch, chemically stable and yet, flexible! It can be bent into an arc or a circle. While doing so, the chemical strain between the atoms changes the electrical bandgap. Researchers believe that this property of Carbyne could lead to its uses in microelectrochemical systems aka MEMS.
Carbyne can also be twisted, but it requires adding methylene molecules at the end of the carbyne chain. Researchers found out that by 'decorating' chains of carbyne with different molecules, several new properties can be introduced in the material. For example, adding calcium atoms at the end of carbyne would turn it into a hydrogen storage sponge.
Just like graphene, carbyne is just one atom thick. What this means is that for its mass, the surface area of carbyne would be 'huge'. You'll be surprised to know that a single gram of graphene, has surface area equal to that of about 5 tennis courts! Researchers believe that this property would be very useful in energy storage mechanisms - where the electrode's surface area is in direct relation to the energy density of the device.
